At the same time, funnyman David took a swipe at Simon Cowell’s ‘moobs’

The funnyman’s post attracted more than 6,000 likes and almost 1,000 re-Tweets.

Yet his fans remained divided over Amanda’s very sexy style.

One remarked: “I think she looks fit! When I grow up I want to be a exactly like Amanda and her awesome rack. Winning in the dress department darling.”

Another posted: “Fantastic dress – she looked amazing. Not sure it was the right choice for the type of programme that’s all,” while a third mused: “Is it a family show…. nothing family about that outfit.”

One cheeky fan then quipped: “Think you should wear something outrageous for the final David!! That would set the Twitter world on fire!! That’s my challenge for you!!”
